Diagnostic Methods for Brain Cancer

Diagnostic Methods for Brain Cancer

Brain cancer is a very difficult-to-treat neurological disease, also known as a brain tumor. Many patients ask the question, can brain cancer be cured? The earlier brain cancer is treated, the better. Do you know what kind of tests and diagnoses are used for brain cancer?

Diagnostic localization of brain cancer treatment

The main diagnosis is based on medical history and physical examination. For example, if there are localized motor seizures on one side of the body, it indicates that the lesion is in the motor area of the contralateral cortex; If the main symptom is motor dysphasia (loss of the ability to express language), it indicates that the tumor is in the posterior part of the left hemisphere; If the main symptom is sensory dysphasia (loss of the ability to comprehend language), brain cancer may be in the posterior part of the left hemisphere temporal gyrus; If there are no seizures, and progressive hemiplegia is the main symptom, it indicates that the brain cancer is in the inner capsule of the brain; If the patient shows endocrine disorders and bilateral temporal hemianopsia, it indicates that it is a saddle area tumor; If the main symptom is limb ataxia, it indicates that the lesion is in the cerebellar hemisphere on that side; If the main symptom is trunk ataxia, it may be a medulloblastoma in the cerebellar vermis. Of course, the diagnostic localization of brain cancer treatment for intracranial tumors is mostly based on the premise of increased intracranial pressure.

Diagnostic confirmation of brain cancer treatment

This refers to the diagnosis of the nature of brain cancer, which is closely related to diagnostic localization. For example, if the diagnostic localization is in the sphenoid sinus, the possibility of a pituitary adenoma is the highest; If the tumor is in the vermiform cerebellar region, the most common is medulloblastoma; If the tumor is in the pontocerebellar angle area, the most common is acoustic neuroma.

It must be pointed out that in some areas such as the anterior one-third of the brain, the anterior lobe of the temporal lobe, or the occipital lobe, tumors can exist for long periods of time or even permanently without showing localized symptoms, only exhibiting increased intracranial pressure. Relying solely on clinical manifestations is not only unable to diagnose the nature of the tumor, it is also difficult to locate it. These regions that are not easily displayed by localized symptoms are called the "silent" or "static" areas of the brain, and auxiliary examinations must be used for diagnosis.

X-ray films, cerebral angiography, ventricular angiography, air-brain angiography, etc. all have diagnostic value. As mentioned earlier, the most ideal auxiliary examination for brain cancer treatment today is CT and MRI, which can not only clearly show the location of the tumor, but also provide important information for qualitative diagnosis.

Radiation therapy mainly utilizes the sensitivity of tumor cells to radiation, which is easily damaged by radiation to kill tumor cells. The general treatment takes about four to eight weeks, and the size and dosage of the irradiation range are determined based on the tumor's pathological diagnosis, differentiation degree, and medical imaging examination results. Currently, the main treatments for brain cancer are surgery, radiation therapy (X-ray, Y-ray), chemotherapy, and biological therapy. Surgery is the preferred treatment for most intracranial tumors, and the use of radiation therapy and chemotherapy after surgery is determined based on the benign or malignant nature of the tumor and the degree of tumor removal.

Above are the diagnosis and testing methods for brain cancer treatment. If you find that you have brain cancer, do not be discouraged. It is important to actively cooperate with medical treatment and maintain a good attitude.
